RDM6300 125KHz cardreader mini-module is designed for reading code from 125KHz card compatible read-only tags and read/write card.

Configuration

Sensor uses serial interface for communication.

Wiring

RDM6300	ESP8266
TX	GPIOx
RX	GPIOy
Pin3	unused
GND	GND
VCC	5V

Tasmota

In the Configuration -> Configure Module page assign:

1. GPIOx to SerBr Tx (71)
2. GPIOy to SerBr Rx (72)

If the RFID Tag is held in front of the Antenna the reader starts sending the Tag ID. The Tag Id is prefaced with a 0x02 and the end is delimited with a 0x03. If the reader reads the tag multiple times you would get one line with multiple times the Tag ID. For this to seperate you can add a SerialDelimiter of 0x03. This will split the result from the serial into serveral single mqtt messages. But (probably) all the messages wil be prepended with a binary 0x02.

Set SerialDelimiter to 3

SerialDelimiter 3
